PISA probably measure some s approximation of G like the SATs but it is an inferior tool for that. G loaded tests measure IQ through time and space better given a broader historical view and if aliens landed on the planet tomorrow they would be able to take the Raven Progressive Matrices we can't say that for PISA. I don't think you understand G at all. PISA is contaminted by culture the disadvantage of culture loaded tests is that they’re less relevant in the long run and that they tend to become obsolete even in their own culture. It’s necessary to renorm them periodically. G has its disadvantages too but since I'm an alien from Mars I'm interested in its intergalactic applicability and since I'm an alien I percieve time and space different from you and I see time as the fourth dimension so the past and future are one hence G rules. Kant demonstrated humans percieve reality through a 3D scaffolding so they don't percieve the Noumenon.
Proficient in math ? Don't make me laugh the vast majority of the population , including scientists and engineers, are not proficient at math because they don't even understand it to begin with. Being proficient in math means publishing new theorems or solving new theorems in mathematics journals. Mathematicians see Engineers as unworthy of knowing real mathematics and scientists are Mathematicians best customers to scientists , engineers and the general public the rules are indtinquishable from mathematics. However, the way a mathematician approaches math is very different.
What is proficient in English or what intelligence level does it take ?
IQ 130-139 — "Gifted"
May just be able to write a legible piece of text like an article or modest novel. Minor literary figures. Ph.D. in the "soft" sciences. In this range lies the mode of scores on high-range tests, and almost 80 % of high-range candidates score I.Q. 130 or higher. Regular psychology's I.Q. tests should not be trusted beyond this range as their validity breaks down here, if such scores are given at all.
What is proficient in science or what intelligence level does it take ?
IQ range 140-149 — Intelligent
Capable of rational communication and scientific work. From this range on, only specific high-range tests should be considered. Important scientific discoveries and advancement are possible from the upper part of this range on.
We do not know if intelligence from about this range on is simply the extreme end of a normal distribution centred at 100 and largely formed by heredity, or if high intelligence in some cases has other causes (non-inherited or non-genetic) which make it deviate from the normal curve centred at 100 and form a "bump" in the far right tail, similar to the bump in the retarded range (which has non-inherited and non-genetic causes). And since we possess no physical, absolute scale of intelligence, these questions are hitherto meaningless altogether.
About one in two high-range test candidates score I.Q. 140 or higher.

School beyond reading , writing and arithmetic is a waste of time for people with IQs above 125 in the modern era with the caveat that education system has a criminal cartel on credentials. Legit smart does not begin until around 125 IQ and that is not even high enough for Mensa. To get college degree, for instance, one only needs 115 IQ :
Half a century of military and civilian research has converged to draw a portrait of occupational opportunity along the IQ continuum. Individuals in the top 5 percent of the adult IQ distrib-ution (above IQ 125) can essentially train themselves, and few occupations are beyond their reach mentally. Persons of average IQ (between 90 and 110) are not competitive for most professional and executive-level work but are easily trained for the bulk of jobs in the American economy. In contrast, adults in the bottom 5 percent of the IQ distri-bution (below 75) are very difficult to train and are not competitive for any occupation on the basis of ability. --Linda Gottfredson

G summarized and wealth is not a good measure of G but there is some correllation :Originally Posted by Grace
By examining the surface characteristics of a great variety of tests in connection with their g loadings, we may arrive at some descriptive generalizations about the common surface features that characterize tests that have relatively high g loadings as compared with tests that have relatively low g loadings. Today we have much more test material to examine for this purpose than was available to Spearman more than half a century ago. This permits broader generalizations about g than Spearnan could safety draw. Spearman characterized the most g-loaded tests essentially as those requiring the subject to grasp relationships—“the eduction of relations and correlates.” That is all perfectly correct. But now we can go further. The g factor is manifested in tests to the degree that they involve mental manipulation of the input elements (“fundaments” in Spearman’s terminology), choice, decision, invention in contrast to reproduction, reproduction in contrast to selection, meaningful memory in contrast to rote memory, long-term memory in contrast to short-term memory, and distinguishing relevant information from irrelevant information in solving complex problems. Although neither the forward nor backward digit-span test of the Wechsler Intelligence Scale, for example, has much g loading. the slightly greater mental manipulation required by backward than by forward recall of the digits more than doubles the g variance in backward as compared with forward digit span (Jensen & Figueroa, 1975). We have seen many examples in which a slight increase in task complexity is accompanied by an increase in the g loading of the task. This is true even for the most mundane and seemingly nonintellectual tasks. Virtually any task involving mental activity that is complex enough to be recognized at the commonsense level as involving some kind of conscious mental effort is substantially g loaded. It is the task’s complexity rather than its content that is most related to g. --AR Jensen
